The present invention relates to a cooling system and, specifically, to a cooling system for a high temperature environment, which cools air in a high temperature environment. According to the present invention, the cooling system includes a heating housing (10) and a cooling housing (20). The heating housing (10) includes: an evaporation unit (100) cooling the air by heat exchange with the ambient air; a compression unit (200) compressing a refrigerant by receiving the refrigerant from the evaporation unit; a condensing unit (300) receiving the refrigerant from the compression unit (200) and condensing the refrigerant by the heat exchange with the ambient air; and an expansion valve (400) expanding the refrigerant passing through the condensing unit (300) and transferring the refrigerant to the evaporation unit (100). The condensing unit (300) is installed by having a first flow path (P1) to exchange the heat between the condensing unit (300) and the external air. The cooling housing (20) is connected to the heating housing (10) and including a cooling air discharge unit (21) discharging the cooling air to the outside after the air sucked from the outside is heat-exchanged with the evaporation unit (100) along a second flow path (P2). The compression unit (200) is installed on the second flow path (P2) formed in the cooling housing (20).
